Fast Magnetic Data Storage

October 15, 2017

Magnetic data storage has long been considered too slow for use in the working memories of computers. Researchers at ETH have now investigated a technique by which magnetic data writing can be done considerably faster and using less energy. Instead of using a current-carrying coil producing a magnetic field to change the direction of magnetization they used an electric current passing through a specially coated semiconductor film. They found that the magnetization inversion happened in less than one nanosecond – considerably faster than in other recently studied techniques. In a first step, the researchers would now like to optimize their materials in order to make the inversion work even faster and at smaller currents.

Frontiers in Biomagnetic Particles Meeting 2017 - Excellent as Always!

October 13, 2017

The 2017 meeting in Asheville, NC, was a great success. This would not be possible without the outstanding talks, posters, and discussions that you can go and check out in the attached abstract booklet here. But it also would not be possible without the energy of the organizers, Jennifer Andrew, Mark Bolding, Thompson Mefford, to again find a great meeting location, excellent invited speakers, and allow for pleasant information exchange and a chance for a good time together. Thank you all!

Successful 5th Colloquium of the DFG Priority Program 1681

October 09, 2017

The 5th Colloquium of the DFG Priority Program 1681: Field controlled particle matrix interactions: synthesis multi-scale modelling and application of magnetic- hybrid materials was held in the Bavarian cloister Benediktbeuern from September 27-29, 2017. This colloquium is part of a special program of the German Research Foundation (DFG), that started in January 2014 and is focused on novel magnetic hybrid materials research. The research ranges from magnetic material production to technical and medical applications and includes modelling of field dependent interaction with different matrices. The large program benefits from the cross-specialization collaboration of chemists, physicist, engineers, biologists, and medics.

Almost 4 years after the start of the program, 86 scientists from each of the 31 projects in the program presented their most recent research findings in scientific talks and posters in the atmosphere of very history-charged walls. The highlight of the annual three-day meeting was, as always, a hiking tour in the mountains that culminates in scientific presentations being given in an alpine hut without any projection equipment. This year, the selected two speakers presented their recently finished dissertations on “Ferrogel actuators for bioapplications” (Emilia Wisotzki, Leipzig) and on “Particle motion investigation by Mössbauer spectroscopy” (Joachim Landers, Duisburg-Essen).

The next colloquium will take place at the end of September 2018, at which time 5 of the 6 years  of the grant period will have elapsed. Planning future research in joint projects will then be in everybody's mind. For more information about this large German grant program, check out:

The Albus Award 2017 Goes to Anna Roig from ICMAB-CSIC

September 06, 2017

Congratulations to Prof. Anna Roig from the Group of Nanoparticles and Nanocomposites, Institut de Ciencia de Materials de Barcelona (ICMAB-CSIC) for obtaining and Albus Grifols Scientific Award.

The Albus Program is an annual international award focused on innovative ideas related to albumin and its role as a therapeutic product. The Program offers two awards of 50,000 € each year. The proposals are assessed by an independent review committee formed by world-wide recognized experts. 
Anna’s “Albumin-iron oxide nanocages” project gets inspiration from the apoferritin nanoconstructs. It aims at investigating if albumin nanocages, consisting of a few units of albumin self-assembled and self-standing, can be formed by using inorganic iron oxide nanoparticles as semi-sacrificial templates. The albumin nanocages could then find application as a nanomedicinal product for imaging and drug delivery.
The winners will be given their Awards at a Ceremony that will take place on October 3rd, 2017 in Barcelona.

Magnetic Microcubes Dance in Magnetic Field

September 03, 2017

A team of researchers including Koohee Han and Orlin D. Velev of North Carolina State University made polymer cubes with 10-µm-long edges and selectively coated one face of each cube with a 100-nm-thick film of cobalt, which can be magnetized. Then they formed aqueous suspensions of the microcubes and showed that by controlling the way magnetic fields were applied to the suspensions, including switching the fields on and off and superimposing fields from multiple electromagnets, the cubes could be made to spontaneously and reversibly assemble in a variety of shapes and patterns (Sci. Adv. 2017, DOI: 10.1126/sciadv.1701108). In some cases, the cubes reversibly switched between a linear chain and ringlike configuration. In others, the cubes underwent complex folding and unfolding.

Experimental Estimation of the Measured Loss Power of Magnetic Nanoparticles

July 27, 2017

In clinical and biomedical applications of magnetic nanoparticle heating, the importance of accurate and precise heating rate measurements cannot be understated. There is currently no standard equipment, methodology, or reference materials to inform and validate data obtained from such measurements. Theoretical modelling relies upon data from such measurements to guide improvements and to distinguish among competing models. Yet, measurement methods vary and are often conducted under conditions that violate the underlying thermodynamic principles upon which the measurement is founded.

Robert Ivkov, Frederik Soetaert et al independently ascertained regions of data that adhere to the thermodynamic criteria, and yet even within these regions significant variability of measurement is observed. Variations within a single measurement actually exceed the variance among replicate measurements. Such variation within the measurements can be attributed to complex magnetohydrodynamic responses of the magnetic fluid and to heat transfer within the sample. Distinguishing between these effects is not possible without additional orthogonal measurements.

Check out this careful and important work for the magnetic hyperthermia community here. It was just published in the journal "Scientific Reports".

The Future of Transport is Magnetic

June 22, 2017

The idea of creating new high-speed mass transit systems is a hot topic for many scientists around the world. Spurred on by technology engineering entrepreneur, Elon Musk, the race is on to create pods that can transport passengers and cargo at high speeds. Musk, the founder and co-founder of several innovative companies including Tesla (premium electric cars), SolarCity (solar energy supply), and PayPal (online payment portal), has inaugurated the Hyperloop project with one of his companies, SpaceX. Although SpaceX was originally set up to explore aerospace manufacture and transport, with the ultimate goal of enabling colonization of other planets, Musk recognized that harnessing the expertise of aeronautical engineers could revolutionize ground transport, and so set up Hyperloop.
The Hyperloop concept is being developed so that pods will travel at very high speeds along a tube, to provide an alternative to flying, rail transportation and driving, while also being safe, convenient and kinder to the environment in not using power that is dependent on fossil fuels. There are several Hyperloop sites being established around the world, and in 2015 Musk launched a competition to encourage the best international student groups to push the boundaries of science and create their ideas of how pods could operate.
Two such top universities, Massachusetts Institute of Technology (MIT, in the US) and Delft University of Technology (TU Delft, in the Netherlands), took part in the first phase of a competition in January this year to unveil their prototype pods at a Hyperloop test track in California. Challenged with a tunnel of one mile in length and six-feet diameter, the teams had to demonstrate that their pods could safely accelerate to speeds of up to 250 mph and break to a standstill without crashing. Both teams used magnetic levitation as their method of propulsion.

Adsorbing nominal amounts of magnetite nanoparticles onto the surface of stiff, anisotropic ceramic particles like alumina enables the fast, parallel control of inorganic architectures with weak, scalable magnetic fields. This ultra-high magnetic response has been exploited to produce complex filler architectures in a new family of advanced composites. For more info, contact Randall Erb. To see the movie, click here.
